+### Additional DateTimeOffset and date/time translations
+
+EF Core 11 adds several new SQL Server translations for `DateTimeOffset`. Properties such as `DateTime`, `UtcDateTime`, and `LocalDateTime` are now translated, allowing you to access the `DateTime` component directly in your queries: `DateTime` returns the date and time component without converting the offset, while `UtcDateTime` and `LocalDateTime` represent UTC and server-local conversions, respectively. `Offset.TotalMinutes` is also translated, giving access to the offset component, and `ToOffset(offset)` allows converting a `DateTimeOffset` to a different offset via SQL Server's `SWITCHOFFSET`.
+
+You can also now construct a `DateTimeOffset` from a `DateTime` directly in LINQ queries, using `new DateTimeOffset(dateTime)` or `new DateTimeOffset(dateTime, offset)`, which translates to SQL Server's `TODATETIMEOFFSET` function.
+
+In addition, `EF.Functions.DateTrunc()` is now available for truncating `DateTime`, `DateTimeOffset`, `DateOnly` and `TimeOnly` values to a specified precision (e.g. day, hour, minute), translating to SQL Server's [`DATETRUNC`](/sql/t-sql/functions/datetrunc-transact-sql) function.
+
+For the complete list of date/time function translations, see the [SQL Server function mappings page](xref:core/providers/sql-server/functions).
